Re: registering as a real protocol - yes this I have been going on about for a while. This needs a few changes in how things work:
1. Register as a real protocol. 2. Change drivers to use netif_rx to receive frames (will also be more efficient) I would also like to see: Drivers to use register_netdev - not special ieee80211 register to register themselves Drivers to use a normal hard_start_xmit function - need to move 802.11 pre xmit frame processing into the qdisc dequeue function Get rid of gunky beacon & multicast buffered frame handling - make them into normal queues like everything else (so same hard_start_xmit can be used).

We also need 802.11 to register as a real protocol, rather than faking ethernet.
